$win->{'tb_icon'} = Wx::TaskBarIcon->new( ); $win->{'tb_icon'}->SetIcon( Wx::GetWxPerlIcon() ); #$win->{'tb_icon'}->RemoveIcon; $win->{'tb_icon'}->Destroy; but this works only under windows, linux gives you a nice memory access error. i think this is a bug further more it cant be destroyed on app shutdown, but maybe i didnt found the solution and have to derive from it or something, cant find it in the dmeo app. thanks for reading
